Feeding Levels

Trophic Levels The feeding levels of an ecosystem. Ecosystems are made up of several feeding levels Each trophic level may contain a variety of species.

Trophic Levels

Questions to consider: Which of the trophic levels has the most energy? The least?

Energy Pyramid

Detailed Energy Pyramid

Energy that enters each trophic level: Mostly used to keep the organism alive Some is passed out as waste Some is stored in the organism’s tissues Available as food for organisms in the next trophic level.

Detritivores Feed at every trophic level Consumers of dead plant/animal matter and animal waste. (Ex. Earthworms, beetles). Also include decomposers such as bacteria and fungi.
